。This is a device that uses the energy of the wind to generate electric power, but since the energy of the wind is small, it can be used for hydropower or thermal power generation.
The current situation is that the installation cost is quite high considering the power generation bath liquid.

計っている。Particularly in the case of kite kites, the production cost of the fork also accounts for a large portion of the cost. For this reason, the windmill is already in production (time production).
The rotor of the Bellycow pig, which has been
We aim to reduce equipment costs by using second-hand items that can be done by hand.

計となっている。However, since the rotor of a helicopter rotates in a horizontal plane and in a few cases has a flexible route, the stress applied to the wings is mainly tensile stress due to the distance of rotation. The design is such that almost no bending stress is applied.
しかし、このロータを風屯痙に使用した場合、喝の回転

な曲げ応力が発生する。However, when this rotor is used for wind turbines, the plane is perpendicular to the rotation of the rotor, so the repeated bending stress due to gravity becomes a force, and the rotor attachment part also becomes rigid, resulting in large bending stress. .

兄の破損につながる恐れがある。In addition, the rotor of a helicopter has a hollow dead surface to reduce direct injection. Therefore, when stress is applied to a large bend, the wing cross-section of the central ram will become @. change,
There is a risk that it may lead to damage to the older brother.

が必要である。Therefore, when a helicopter rotor is used as a wind turbine blade, it is necessary to take measures to strengthen the rotor to reduce the bending stress by 1j.

16 ``Using a rotor for a used helicopter that has been in use for one year, and filling the inside of the wing with materials such as resin-necked foam plastic and next month, light metal, etc.'' The 11 rotors are characterized by having excellent strength against bending due to bending stress without completely losing the strength of the rotor.
本発明に、風東用翼としてヘリコプタのロータを用いた
場合、強度上の不安点を取り除き、粱としての信頼件向
十を言するものである。In the present invention, when a helicopter rotor is used as a wing for use in the wind direction, concerns about strength are eliminated, and the reliability of the rotor is improved.
